食管曲张静脉破裂出血者采用硬化剂注射治疗日益增多,因此法简单而又能提高生存率。早期的研究是作硬化剂粘膜下注射,旨在局部闭塞曲张静脉。尽管曲张静脉内与曲张静脉旁注射没有直接的比较研究,但有人报告:曲张静脉旁注射在远期效果上并无益处;另有研究提示理想的注射部位是曲张血管本身。本文 Esophageal variceal bleeding with sclerotherapy injection treatment is increasing, so the method is simple and can improve the survival rate. Early research was used as a sclerostat submucosal injection, designed to partially occlude the varicose veins. Although there is no direct comparative study of varicosities and paraventricular injections, it has been reported that paraventric paraventricular injection has no beneficial effect on long-term outcomes. Another study suggests that the ideal injection site is varicose veins. This article
